Fig. 4From: Enhanced expression of the stemness-related factors OCT4, SOX15 and TWIST1 in ectopic endometrium of endometriosis patientsRelative mRNA expression levels in 49 paired cases with endometriosis. Quantitative Real Time PCR was used to analyze the mRNA expression levels of OCT4 (a), SOX15 (b), and TWIST1 (c). Expression levels were normalized to ß-actin and GAPDH. Expression levels were shown as mean ± SD. All p-values were analysed by paired t-testBack to article page
